Pfas, or per- and polyfluoroalkyl substances, are a group of human-made chemicals found in everything from food packaging to firefighting foam. Often called “forever chemicals” due to their persistence in the environment, they can affect our health and disrupt our immune system.
Pfas cross the placenta, so that when a woman is pregnant, she shares some of the Pfas in her body with her unborn child. While most of us are routinely exposed to low levels of Pfas, some communities are exposed to far higher levels from nearby pollution sources, like factories and military fire training areas.
